A CNN article from June of this year describes road blocks at several points in 2 Alabama towns. For 2 days, off duty St. Claire County deputy sheriffs flagged motorists down, steering them toward federal highway safety researchers. The motorists were asked questions about drinking, drug use, and then asked for breath samples, as well as paid saliva and blood samples. These were part of a national study conducted by the National Highway Traffic Safety Administration.

In Fort Worth, Texas, drivers were stopped by a police road block where, as in the previous story, they were asked for breath, saliva and blood samples. It was part of a government research study that sought to determine the number of drunken or drug impaired drivers.

Vic also presented an NBC audio track that gave details of a road block stop where a woman was offered $10 for cheek swabs and $50 to give a blood sample.

Vic brought up a very important question: Are these drivers responding under the law or is this a commercial contracting job that allows someone posing as law enforcement to display assumed authority so they can pull you off the road?
